Moments of Genius - Samuel West

Actor Samuel West describes his favourite moment in the history of science. Why things burn, why we have any weather at all, why everything living tends to die: these are just a few of the questions that are answered by the rather prosaically named, Second Law of Thermodynamics. The Second Law states that, energy-wise, everything tends to chaos. It's a law of physics but also a personal motto for actor, Samuel West.
